QuestionWhich set of side lengths represents a triangle with 3 lines of reflectional symmetry? 3,4,5 3, 6, 9 5, 5, 5 $5,10,5$

Studdy Solution
The set of side lengths that represents an equilateral triangle, and thus has 3 lines of reflectional symmetry, is:
$$5, 5, 5$$
The set of side lengths representing a triangle with 3 lines of reflectional symmetry is:
$$\boxed{5, 5, 5}$$
